Intelligent integrated low-voltage permanent magnet vacuum circuit breaker

The intelligent integrated low-voltage permanent magnet vacuum circuit breaker comprises an insulating main cavity, a middle partition plate is arranged in the insulating main cavity and divides the insulating main cavity into a front side and a rear side, the front side of the insulating main cavity is provided with a vacuum arc extinguish chamber and a first grid cavity in the vertical direction, and a static contact of the vacuum arc extinguish chamber is connected with a static end red copper contact. The moving contact extends into the first grid cavity and is connected with an insulator, and the end face of the insulator is connected with a left output shaft of the permanent magnet operating mechanism. A displacement sheet metal part is fixed to the end face of the insulator, and a photoelectric sensor used for monitoring the displacement sheet metal part is arranged in the first grid cavity. The rear side of the insulating main cavity is provided with a moving end red copper contact, the middle part of
